Step Inside the New Aboard T4 Travel Trailer

The Aboard T4 is a new hybrid-electric smart travel trailer designed to bring more comfort, flexibility and energy independence to life on the road and off the grid.

At Demo Days 2026, Seeing Green stepped inside the T4 for a sneak peek at the 25-foot travel trailer. We explore its two dinettes, kitchen with induction cooktop and deep sink, dual-entry mudroom-style bathroom and panoramic rear living space, where a power tailgate opens the entire back wall to the outdoors.

Underneath it all is a 200-kilowatt-hour energy system with an onboard range extender, designed to generate, store and manage power on the road or off the grid and even send power back to an electric tow vehicle.

The Aboard T4 sleeps four and is expected to begin deliveries in 2027.
